Low Temperature Behavior of Asphaltite Modified Binders and Asphalt Concretes

open access: yesLecture Notes in Civil Engineering, 2020
Natural asphalts are often used as stiffeners to obtain hard bitumens. With the decrease of the global production of hard bitumens, the use of natural asphalts as stiffeners becomes increasingly interesting.

In Situ Rb/Sr Geochronology and Stable Isotope Geochemistry Evidence for Neoproterozoic and Paleozoic Fracture‐Hosted Fluid Flow and Microbial Activity in Paleoproterozoic Basement, SW Sweden

open access: yesGeochemistry, Geophysics, Geosystems, Volume 24, Issue 5, May 2023., 2023
Abstract Recent studies have shown that biosignatures of ancient microbial life exist in mineral coatings in deep bedrock fractures of Precambrian cratons, but such surveys have been few and far between. Here, we report results from southwestern Sweden in an area of 1.6–1.5 Ga Paleoproterozoic rocks heavily reworked by the 1.14–0.96 Ga Sveconorwegian ...

Fish Fingerprinting: Identifying Crude Oil Pollutants using Bicyclic Sesquiterpanes (Bicyclanes) in the Tissues of Exposed Fish

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 1, Page 7-18, January 2023., 2023
Abstract In the present study, we investigated the possibility of identifying the source oils of exposed fish using ratios of bicyclic sesquiterpane (bicyclane) chemical biomarkers. In the event of an oil spill, identification of source oil(s) for assessment, or for litigation purposes, typically uses diagnostic ratios of chemical biomarkers to produce
